Fiat 500X 2021 Owner's Manual page 129

CAUTION!
Do not tow a trailer at all during the first

500 miles (805 km) the new vehicle is
driven. The engine, axle or other parts could
be damaged.
Then, during the first 500 miles (805 km)

that a trailer is towed, do not drive over
50 mph (80 km/h) and do not make starts
at full throttle. This helps the engine and
other parts of the vehicle wear in at the
heavier loads.
Towing Requirements — Tires
Do not attempt to tow a trailer while using a

compact spare tire.
Proper tire inflation pressures are essential

to the safe and satisfactory operation of your
vehicle Ú page 296.
Check the trailer tires for proper tire inflation

pressures before trailer usage.
Check for signs of tire wear or visible tire

damage before towing a trailer Ú page 296.
For the proper tire replacement procedures

Ú page 296. Replacing tires with a higher
load carrying capacity will not increase the
vehicle's GVWR and GAWR limits.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake

system or vacuum system of your vehicle
with that of the trailer. This could cause inad-
equate braking and possible personal injury.
An electronically actuated trailer brake

controller is required when towing a trailer
with electronically actuated brakes. When
towing a trailer equipped with a hydraulic
surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers

over 1,000 lbs (453 kg) and required for
trailers in excess of 2,000 lbs (907 kg).
STARTING AND OPERATING
WARNING!
Do not connect trailer brakes to your

vehicle's hydraulic brake lines. It can over-
load your brake system and cause it to fail.
You might not have brakes when you need
them and could have a collision.
Towing any trailer will increase your stop-

ping distance. When towing you should
allow for additional space between your
vehicle and the vehicle in front of you.
Failure to do so could result in a collision.
CAUTION!
If the trailer weighs more than 1,000 lbs
(453 kg) loaded, it should have its own
brakes and they should be of adequate
capacity. Failure to do this could lead to accel-
erated brake lining wear, higher brake pedal
effort, and longer stopping distances.
